| .. _amdgpu_synid_gfx11_waitcnt: |
| |
| waitcnt |
| ======= |
| |
| Counts of outstanding instructions to wait for. |
| |
| The bits of this operand have the following meaning: |
| |
| ===== ================================================ ============ |
| Bits Description Value Range |
| ===== ================================================ ============ |
| 2:0 EXP_CNT: export and LDSDIR count. 0..7 |
| 3:3 Unused \- |
| 9:4 LGKM_CNT: LDS, GDS, Constant and Message count. 0..63 |
| 15:10 VM_CNT: vector memory operations count. 0..63 |
| ===== ================================================ ============ |
| |
| This operand may be specified as one of the following: |
| |
| * An :ref:`integer_number<amdgpu_synid_integer_number>` or an :ref:`absolute_expression<amdgpu_synid_absolute_expression>`. The value must be in the range from 0 to 0xFFFF. |
| * A combination of *vmcnt*, *expcnt*, *lgkmcnt* and other values described below. |
| |
| ====================== ====================================================================== |
| Syntax Description |
| ====================== ====================================================================== |
| vmcnt(<*N*>) A VM_CNT value. *N* must not exceed the largest VM_CNT value. |
| expcnt(<*N*>) An EXP_CNT value. *N* must not exceed the largest EXP_CNT value. |
| lgkmcnt(<*N*>) An LGKM_CNT value. *N* must not exceed the largest LGKM_CNT value. |
| vmcnt_sat(<*N*>) A VM_CNT value computed as min(*N*, the largest VM_CNT value). |
| expcnt_sat(<*N*>) An EXP_CNT value computed as min(*N*, the largest EXP_CNT value). |
| lgkmcnt_sat(<*N*>) An LGKM_CNT value computed as min(*N*, the largest LGKM_CNT value). |
| ====================== ====================================================================== |
| |
| These values may be specified in any order. Spaces, ampersands, and commas may be used as optional separators. |
| If some values are omitted, the corresponding fields will default to their maximum value. |
| |
| *N* is either an |
| :ref:`integer number<amdgpu_synid_integer_number>` or an |
| :ref:`absolute expression<amdgpu_synid_absolute_expression>`. |
